A vaccine reaction is any injury or condition that occurs as a result of a vaccination that has been given to protect against disease. Serious reactions to vaccines are very rare, and vaccination is far less risky than the catching the disease it prevents. Reference from A.D.A.M.
The United States Marine Corps (USMC), also known as the United States Marines, is a branch of the United States Armed Forces responsible for providing power projection, using the mobility of the United States Navy, by Congressional mandate, to deliver rapidly, combined-arms task forces on land, at sea, and in the air.
As part of the world's most elite fighting force, a Marine is primarily a warrior, skilled in the art of warfare.
